Ficus Lyrata problems or normal behaviour?

Hello,

we purchased this wonderful ficus a few months ago. We noticed the red veins on leaves and the wrinkled parts when purchasing, but the seller guaranteed that this is perfectly normal for this plant. We also started seeing some black spots that kinda look like mold spots, they can be removed by cleaning, but still, is this something to worry about? Please let me know if all of the mentioned things are cause for concern or it should be like that. Thank you so much!
